111K COUNTER FOR- INTER-FOLDING MACHINES,

Application filed Octobe 1. 1822. Serial. No. 594,062.

To all whom it may concern Be it known that I, LOUIS A. Srnaunnn, a citizen of the United States, and resident of Green Bay, in the county of Brown and State of Wisconsin, have invented'certain new and useful Improvements in Ink Counters for Interfolding Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to improvements in paper folding machines and more particularly to machines employed in producing packages containing a plurality. of folded sheets, such as toilet paper, paper toweling, and the like.

The primary object of the invention resides in the provision of a simple and accurate counting mechanism adapted to mark the work material at predetermined intervals as it passes through the machine.

.A further object is to provide an ink marker which, prior to each marking operation, is adapted to pass over an inking pad.

A more specific object resides in the provision of means for gradually conveying the inking device across the inking pad, and ad ditional means for momentarily effecting the marking operation.

With the above and other objects in view, which will appear as the description pro ceeds, the invention resides in the novel con struction, combination and arrangement of parts, substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawing is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof, and in which Figure 1 is a fragmentary View of a paper folding machine showing the present invention attached thereto, and

Figure 2 is a plan View of the same.

Referring more particularly to the accompanying drawings. the numeral 1 designates one of the side frames of an interfolding machine, in which are j ournaled the cus tomary rolls, indicated by dotted lines, through which the work material passes, the latter designated by the letter A.

The present invention comprises a marker 2, preferably constructed as a roller journaled on the end of the arm 3, which is pivotally mounted on a stud 4 carried by the side frame 1. Positioned within the path of travel of the marker 2 is an inked pad 5 of conventional structure, which is supported by a resilient arm 6 suitably attached to a stationary part of the folding machine.

Secured to the side frame 1 is a bracket 7 which carries the stud 8 having journaled thereon a toothed ratchet wheel 9 to which is connected, in any suitable manner, the cam 10, the latter engaging the pivotal arm 3 for the purpose of actuating the arm and causing the marker to travel back and forth across the inking pad, the arm 3 being held against the cam 10 by means of the spring 11. Secured on the arm 3 is a hardened steel lug 12, which is engaged by the trip plate 13 adjustably mounted on the cam 10 by means of a screw and slot connection.

For the purpose of intermittently actuating the ratchet wheel 9, the lever 14 is loosely journaled on the stud S and carries a pivotal pawl 15 which engages the teeth of the ratchet wheel. Oscillatory movement is transmitted to the lever 14: by means of the connecting link 16 which is mounted on an eccentric 17 carried by the shaft 18, which is journaled in side frame 1 and carries one of the work rolls employed in operation upon the work material.

Taking up the operation of the device, it will be apparent that through the eccentric and link mechanism oscillating movement is transmitted to the lever 14, which in turn intermittently rotates the ratchet wheel 9, one tooth at a time, by means of the pawl 15. As the rachet wheel is rotated, the cam 10, which is in the form of an eccentric, imparts a comparatively gradual and slow movement to the marker arm 3, causing the roller 2 to pass across the pad 5 and receive a fresh coating of ink. Inasmuch as the arm 6 is preferably formed of resilient material, the relative position of the pad may be so adjusted as to insure proper contact with the roller 2 at all times.

In the relative position of the various parts, as illustrated in Figure 1, the roller 2 has traveled over the inking pad and is in a position adjacent the work material. At this point the trip plate 3 is so adjusted as to momentarily engage the lug 12 causing a quick depression of the marker as it momentarily engages the work material after which lOU the trip plate passes over the lug and the spring 11 returns the arm 3 to its normal position engaging the cam 10. The quick movement of the marker thus derived during the work engag ng movement is very essential, in that it is desirable to place only a small mark on the paper, (and due to the speed at which the work material travels, this could not be accomplished were its movement prolonged for any considerable period.

In connection with the marking operation, attention is directed to the fact that wear between the various arts of the machine -is compensated for by the adjustment provided for the trip plate. It will further be seen that the frictional drag oi"- the arm 3 upon the cam 10 caused by the spring 11 will prevent overthrow of the cam which might otherwise be causec-through the pawl feed of the ratchet, thus assuring an accurate count, which count can he altered or regulated by varying the number of ratchet teeth or increasing the throw of the lever 14.

From the foregoing description taken in connection with the drawings, it will be obvious that a very simple and eiiicient device has been provided for accurately marking the work material at predetermined intervals, and other than the comparatively short movement of the marker during the marking'operation, the mechanism is permitted to operate at a gradual speed thus eliminating wear of the parts and possibility of their disaline'ment. v

While I haveshown and descriheda specific form of mechanism for actuating the cam and trip plate 13, it will he understood that various structures for this purpose are contemplated, as within the scope of the in vention.

I claim 2- 1. In a paper folding machine, the combination of an automatic mechanism for marking the work material at predetermined inervals, no

pad prior to enga, ngthe work mateial, cam for gradually feeding the roller across said pad, and means carried by the cam "for momentarily forcing the roller against the work material,

in a paper folding machine, the combination or" an automatic mechanism for markthe work material at predetermined intervals, said mechanismcomprising an inking pad. an ink marker adapted to pass over said pad prior to engaging the work mate* rial, a cam tor gradually feeding the marker across said pad, a lug carried by the marker, and means associated with the cam for momentarily engaging saidlug to force the marker against the work material.

a, In a paper folding machine, the combiion of an automatic mechanism for mark ing the work material at predetermined intervals, said mechanism comprising an ink ing pad, a movable arm provided with an ink marker, a cam engaging said arm to carry the marker across said pad, a lug connected to said arm, means associated with the for momentarily engaging said lug to force the marker into engagement with the work material, and means for actuating said cam.

In testimony that I claim the foregoing I have hereunto set my hand at GreenBay, in the county of Brown and 'Stateot lvisconsin. 7 V
